Hi. just tried to fire up the central heating side of my combi, but no joy.
it fires up and heats the water but it does not circulate. i have good sytem pressure, and light on for the pump and safety thermostat activated. (not flashing). does anyone think the pump might have seized, as on our old boiler we had to give it a tap at the start of winter. to get it going?. all answer gratefully received .
